When you are describing the rate that a race car goes around a track should you use the term speed or velocity to describe the motion?

Since velocity is speed with direction, you would use speed in reference to average rate of change of position, since the direction keeps changing. You can use velocity in reference to instantaneous speed, since a car is going in a specific direction at each instant in time.
Examples:
80 km/h is a speed.
80 km/h due north is a velocity.

How does velocity describe motion?
Velocity is a measure of the change in location (or motion) per unit f time.
Which term can describe both speed and direction of an object motion?
velocity
What can describe both the speed and direction of an object's motion?
the object's velocity
What term can describe both the speed and direction of an object's motion?
Velocity
Is Velocity any change in motion?
Yes. Acceleration is a change in velocity; velocity is a change in speed and or direction. I am not sure what motion means in a technical sense (velocity?).
Science of describing the motion of objects?
velocity
How does velocity describe motion?
Velocity is a measure of the change in location (or motion) per unit f time.
What is the term to describe motion when different observers see the same motion differently?
Relative velocity/motion
What are needed to completely describe velocity?
Speed and direction of motion.

What term can best describe both speed and direction of an objects motion?
That is called "velocity".
Why speed is considered as incomplete quantity to describe motion?
Because it doesn't have direction - Velocity is usually used to describe motion in physics because it has both speed and direction.
What kind of motion is describing when the vehicle running at the speed of 50 kilometers per hour going to north?
The answer depends on the degree of complexity you want to put into it. At the simplest, it is linear motion at constant velocity due North. A more complicated version is that it is motion in a circular arc around the globe: heading at a constant speed towards the North pole. It is no longer a velocity because the direction is changing.
